Whelping Pool Cover lovingly handmade with fleece material. SMALL size - bottom circle measures 28" across, top rim measures 36" across, and the sides are approximately 8" high. Secured with elastic all the way around the circumference to hold the cover in place while mom "digs" and gets things ready. Bright Floral - Coral Cloud Bottom *photos show a medium but this listing is for a small size cover in the same design. Using this cover protects pups from getting lost beneath a blanket and possibly missing out on a feeding or two. I also use pool noodles (see photo) underneath as a bumper to protect pups from getting accidentally crushed by mom. I use puppy pads underneath to absorb moisture. The nice thing about fleece is that liquid will flow through to the pads and keep puppies nice and dry. Machine wash and dry. I rotate 4 of them so I can wash the three dirty covers in one load. The pool and noodles are not included! The other photos are of covers in use with my Golden Retriever, "Miss Daisy Ray of Sunshine", and her litter. Make sure to measure your pool - there are 3 different sizes.
